A federal judge paused the Trump administration’s demand that colleges in 17 states submit expanded student race and admissions data under the Admissions and Consumer Transparency Supplement (ACTS). U.S. District Judge F. Dennis Saylor IV of the District of Massachusetts issued a preliminary injunction after finding the mandate likely unlawful and that colleges would face immediate, irreparable administrative harm. The ruling applies only to public institutions in the states that jointly sued the Education Department and the Office of Management and Budget. The lawsuit argued the requirement was “arbitrary and capricious,” with an accelerated implementation deadline that the judge said appeared designed to force compliance. ACTS would have required selected four-year colleges to provide detailed applicant, admitted, and enrolled-student information—including race, gender, grades, standardized-test scores, and family income—covering seven admission cycles. The Education Department previously said it would add ACTS to IPEDS, the annual reporting system colleges must complete. The injunction extends a fast-moving legal battle over how higher education will respond to post–SFFA v. Harvard admissions transparency initiatives—and signals that new federal data collection could face continued court scrutiny.
